NI Vision does not support reading JPEG2000 files with this colorspace method

[Brooks_LV]

Hi NI,

I am trying to read two JPEG2000 file's using the IMAQ Read File.vi.  Here's the history and background for both files:

1. The first file is being read using the IMAQ Read File.vi and it errors with error code -1074395974.

2. The second file is a product of the first file being read into PhotoShop and then saved to disk.  It is being read using IMAQ Read File.vi and it errors with error code: -1074395989.

The help file says that the IMAQ Read File.vi can read JPEG2000 files.  Any idea why it is erroring?

Thanks,

Brooks

Photoshop and other programs that write JPEG2000 files often encode the file with multiple layers and we only support single-layered JPEG2000 files. If you need a lossless encoding format I would move towards PNG.
